Media boss longing to get spinning (7)
I believe the answer is:
eddying
'spinning' is the definition.
The answer and definition can be both to do with motion as well as being present participle verbs.
Perhaps there's an association between them I don't understand?
'media boss longing' is the wordplay.
'media boss' becomes 'ed' (short for editor).
'longing' becomes 'dying' (dying is a kind of longing).
'ed'+'dying'='EDDYING'
'to get' is the link.
Can you help me to learn more?
(Other definitions for eddying that I've seen before include "in vortex" , "Swirling around" , "Swirling round" .)
